This PR adds undo functionality so you can restore the state of your
constraint if you make a mistake. We also amend the autosave
functionality to only apply when values are changed and you have a valid
value. See demo:

This PR removes the cancel button from the new constraint accordion.
Since we now do autosave when the constraint updates, cancel is no
longer needed, the done button and delete button is enough.
This PR adds autosave to the constraint accordion which means that when
you add values to it, it will automatically save the constraint locally.
If you unmount the constraint component without any valid values, it
will remove the constraint from the list.
